How to install Installing the product Installation & safety instructions Mounting Boxes MK Elements Collection Installation Guide by Honeywell This product must be installed by a competent person (e.g. a qualified electrician) in accordance with these instructions and the appropriate current national wiring regulations (e.g. the IEE Wiring Regulations BS 7671). To prevent the risk of electrocution it is essential to disconnect the main electricity supply before commencing installation or maintenance work. Do not work on this product ‘live’. Do not use electric screwdrivers or power tools to tighten the product It is essential that all connections to the terminals are made as instructed, that cables are not stressed and all terminal screws are fully tightened. When earth terminals are present they must always be used. On wall mounted products ensure product is screwed securely to its mounting box before turning on the mains supply. To prevent fire hazard do not exceed the maximum rated current of the unit. The MK Elements Collection products consist of the main product module, complete with its support frame, plus a separate clip on frontplate. The product is mounted to the wall, after wiring, and the frontplate is clipped onto the frame. The frontplate is supplied separately to aid installation. Note: Switched Socket Outlets and Switches with built in LED locators and indicators must be removed from the circuit before insulation testing can be carried out. The MK Elements Collection wiring devices are designed to fit into folded metal boxes that comply with BS 4662. To ensure products can be correctly installed, the box must always be installed flush or sub flush to the surface to a maximum depth of 6mm. To ensure a safe installation, you must read all the installation & safety instructions on page 1 Steps for installation : 1. Ensure the depth of the back box is correct for the product and that it is fitted securely to the wall. 2. Install the cables in the normal way and, using the fixing screws supplied, mount the product, without the frontplate, to the wall. It is important the correct headed screws are used as any other may clash with the rear of the front plate. Switches incorporating a “LOOP” terminal are intended for connection of unused Neutral conductors only. 3. To optimise frontplate installation do not over tighten the screws. Adjust so the frame and module sit squarely on the wall. 4. Fit the frontplate as shown on page 4,5. Note: Care should be taken to ensure product features such as snap fits are not blocked during installation or decorating, preventing correct fitting of frontplates (for example plaster, tile grout, paint etc). When carrying out insulation resistance testing, first disconnect any product which features illumination. Failing to do this could damage the product and could also give spurious insulation readings. Fitting and removing the frontplate Fitting the frontplate 2 1 Removing the frontplate Connection Load/supply cables Strip back the sheath of the cable by the required amount. Strip back the insulation of the individual conductors by the required amount. Insert the conductors into the respective terminals. Where products are supplied with backed out terminal screws, do not loosen screws further. If the earth conductor is bare copper, ensure it is covered with a green/yellow sleeve, so it cannot touch live parts. Carefully push the wired product into the mounting box ensuring the cables are not trapped or pinched. Ensure all the terminal screws are tightened securely with a 4mm wide screwdriver. Pull on each cable to ensure the terminal screw has securely fixed the conductor. Data products in euro mounting frames Products operating at extra low voltage levels (<50V) must not be mounted in the same euro enclosures as equipment rated in excess of 50v (e.g. mains socket outlets). Carefully insert a 4mm screwdriver into the slots provided along the bottom edge of the frontplate Carefully twist the screwdriver and lift the frontplate away disengaging the snap fits 2 1 1 2 4 5 6 3 Recommended Mounting Box Minimum Depths : Socket outlets 35mm German style 2 pole + E Socket outlet 47mm (except K34384 : 35 mm) Connection units 35mm Plate switches 35mm Telephone, television and data outlets 35mm Grid switches 35mm High Current Switches 47mm Shaver supply units 47mm Rotary dimmer 35mm Some mounting boxes are fitted with additional threaded fixing lugs on the upper and lower edges. It may be necessary to bend these back into the box to ensure the frontplate sits flush with the mounting surface. The MK Elements Euro Module wiring devices range offers a variety of clip in modules, telephone, data connectors etc, providing the flexibility to customise a wiring device in the same enclosure and frontplate. Care must be taken to ensure that segregation is maintained between modules of different operating voltages in accordance with the current edition of the IEE Wiring Regulations (BS 7671). 1. Locate the top and bottom hooks on the back of the frontplate into the holes on the top and bottom of the module 2. Gently push along the top edge of the frontplate followed by the bottom edge. Note: Ensure the correct frontplate is fitted to the correct module or frame.
